Title: Improvements in or relating to electric lampholders
IPC: H01R33/00
Filed: 1956-08-17
Abstract: 800,059. Lamp-holders. WARD & GOLDSTONE, Ltd., and HOLT, H. May 16, 1957 [Aug. 17, 1956], No. 25177/56. Class 38 (1). A lamp holder for mounting in an aperture in a panel comprises a resilient insulating body 10 having a flange 11 adjacent one end and integral claws 20 formed on said end adapted for snapfastener engagement in the aperture. A metal shell 21 is retained in the body by tongues 23 thereon which engage recesses 24 in the body and a central contact is carried by an insulating bush 25 backed by a spring 26. Where the holder provides an earth return through the panel, the shell 21 carries tongues 31 at its outer end which are bent over to lie between the claws 20 and contact the edge of the aperture. Alternatively a tongue 34, Fig. 8, on the shell may project from the rear of the body 10 for connection to a separate return lead 36. In either case, the shell may be formed with bayonet slots 42 or integral projections 44 arranged helically to form a screw thread.

Abstract: 1398405 Animal feed composition SMITH KLINE & FRENCH LABORATORIES Ltd 24 May 1973 [30 May 1972] 25268/72 Heading A2B A ruminant feed composition contains 5- 80% by wt. of finely divided roughage and 0.01-0.2% by wt. of a non-ionic surface active agent, the roughage having a modulus of fineness of 2.0-4.0 and a modulus of uniformity of 0:4:6-4:6:0. The roughage is preferably prepared by passing barley straw through a hammer mill having an outlet screen of size #-¢". The surface active agent is preferably a polyoxyalkylene polyol block copolymer based on a hydrophobic polyoxypropylene polymer of molecular wt. 900-3150 on to which has been polymerised ethylene oxide to obtain hydrophilic polyethylene oxide in an amount of 20-90% of the final M.W. of the product.

Patent GB-788373-A (GB)
Title: Water-soluble derivatives of 5-nitro furfural and production thereof
IPC: C07D295/02
Filed: 1955-09-05
Abstract: The invention comprises addition compounds of two mols. of a piperazine and one mol. of 5-nitro - furfural semicarbazone, N - (5 - nitro-2 - furfurylidene) - 1 - aminohydantoine or N-(5-nitro - 2 - furfurylidene) - 3 - amino oxazolidone.  The novel compounds may be prepared by reacting a piperazine with one of the abovementioned 5-nitro-furfurylidene compounds in the molar proportion of 2:1 in an inert diluent, for example water or an anhydrous organic medium such as pure ethanol, at an elevated temperature below 100 DEG  C., say about 80 DEG  C., after which the reaction mixture may be evaporated to dryness in the presence of a dehydrating agent.  It is desirable to evaporate the reaction solution in vacuum to obtain a syrup and then to spread the latter in film form, say over plates, and complete drying in a vacuum over sulphuric acid.  Piperazine may be used in the form of piperazine hydrate.  Alkyl piperazines such as methyl and dimethyl piperazines may also be used.  The products are useful water-soluble bactericidal compounds (see Group VI).ALSO:A bactericidal composition comprises an aqueous solution of an addition compound of 2 mols. of piperazine, or an alkyl piperazine, and 1 mol. of 5-nitro-furfural semicarbazone, N - (5 - nitro - 2 - furfurylidene) - 1 - aminohydantoine or N - (5 - nitro - 2 - furfurylidene)-3-amino oxazolidone (for preparation see Group IV (b)).  The compositions are useful for preventing and curing infectious diseases of poultry.  Thus the addition compounds of piperazine and either 5-nitrofurfural-semicarbazone or N - (5 - nitro - 2 - furfurylidene) 3-amine oxazolidone in doses of 1.5 gm. per 100 gm. of water are active against coccidiosis, pullorosis and diphtheria of poultry.  The aqueous solutions may also be used for treating bee dysentery.  A syrup of 100 gm. of an aqueous solution containing 1.5 per cent of the addition compound, and 90 gm. of sugar is suitable for this purpose.  Aqueous solutions containing 1 part of an addition compound of piperazine and 5-nitro-furfural semicarbazone in 150,000 parts of water prevent the development of cocci, anaerobia and Gram positive bacilli, and provide a good disinfectant for wounds.

Title: A process for the production of carbon disulphide
IPC: C01B31/26
Filed: 1929-08-21
Abstract: 331,734. Imperial Chemical Industries, Ltd., Fletcher, W. B., Wheeler, T. S., and McAulay, J. Aug. 21, 1929. Carbon disulphide is made by heating hydrocarbons, such as methane, with sulphur vapour at temperatures above 1100‹ C., at which no carbon oxysulphide is formed. Coal gas, coke oven gas, gases from hydrogenization of carbonaceous materials &c. may be used as the source of hydrocarbon, and may be diluted with hydrogen or other inert gas. The gases may be preheated to a temperature of 600-800‹ C., and sulphur vapour mixed therewith. Molten sulphur may be introduced through a silica tube heated to about 1400‹ C. Sulphur or hydrogen sulphide is recovered from the exit gases by condensation or reaction with hydrogen, and is returned with a fresh supply of sulphur vapour, or the hydrogen sulphide may be absorbed, say. by iron oxide, which may be regenerated by treatment with the inlet gases containing hydrogen and hydrocarbons. According to the Provisional Specification hydrogen sulphide may be used instead of sulphur vapour. Specification 293.172 is referred to.

Abstract: 1,125,890. Regulating. DAIMLER-BENZ A.G. June 7, 1967 June 7, 1966], No.26209/67. Heading F1B. In a multi-fuel engine having a turbo-charger 2 and an injection pump 8, the travel of the fuel delivery control rod 10 is limited by a full-load stop 11 which is automatically adjustable by a device 12 actuated in dependence, on the one hand, on engine speed and, on the other hand, on the charging pressure and/or upon the exhaust gas temperature upstream of the turbine 3. Stop 11 is moved by a spring-loaded piston rod 14 acted on by the delivery air pressure in space 16. Space 18 is connected to a pressure intensifier 20 controlled by a bellows 20a which is compressed by a rod 21 carrying a roller 22 engaging a cam 23 displaceable by an engine-driven centrifugal governor 24. Operation: With a diesel fuel supply the stop 11 is set to give a predetermined maximum delivery of fuel in the full-load position. With petrol fuel the pressure in pipe 7 and space 16 is reduced thereby moving the stop 11 in the direction of arrow 25 allowing the rod 10 to move in the direction of arrow 26 thus permitting a greater fuel delivery at full load. In an alternative embodiment (not illustrated) the position of the stop 11 is adjusted in dependence on engine speed and upon the exhaust gas temperature upstream of the turbine 3 sensed by a temperature-responsive element which either senses the temperature or a pressure dependent on that temperature. Stop 11 may be constructed as a three-dimensional cam which is rotatable by the temperature-responsive element in the direction opposite to the arrow 26 if the temperature rises excessively. The arrangement shown may have stop 11 arranged as a three-dimensional cam which is rotatable in dependence on the temperature of the exhaust gas upstream of the turbine 3. The stop 11 arranged as a three-dimensional cam may be adjusted in dependence upon the combustion air temperature upstream of the compressor 6.
